FRONT GUN SIGHT.

Application filed Sephmber 25, 1920. Serial No. 412,782.

T 0 all whom it may concern:

Be it known that I, LEWIS H. BRADLEY, a citizen of the United States of America, residing at Hartford, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Front Gun Sights, of which the following is a specification.

This invention relates to improvements in gun sights, particularly for use upon shotguns.

An object of the invention is to provide a front gun sight that can be readily and securely attached to the outer end of the barrel so that when the gun is discharged there is no danger of the sight being blown out, as often happens with gun sights as now constructed and secured.

A further object is to provide a front gun sight which Will be brought down close to the barrel when in place, thereby enabling the user to be sure that only the sight is visi ble and not the securing means.

I-Ieretofore it has been the common practice to secure the outer sight by simply forming a tapered opening in the barrel and having the pin which is secured to the sight piece tapered to make a driving fit in the opening. As a result of this construction the pin often loosens and blows out when the firearm is discharged, resulting in the loss of the sight.

The present invention comprises a sight having its securing pin threaded to fit a threaded opening in the end of the barrel, as will be fully shown and described.

Referring to the drawings which form a part of the specification:

Fig. 1 is a plan view showing a portion of the outer end of the barrel with the sight in place.

Fig. 2 is a partial longitudinal sectional view of the barrel showing the sight partially in section and the forward end in full lines.

Fig. 3 is a perspective view, clearly illustrating the manner of securing the sight in place.

Referring to the drawings in detail: 1 indicates the outer end portion of the shot gun, 2 the bore thereof. Formed in the upper part of the barrel is a threaded opening 3 to receive the threaded pin or stem t of the sight which is formed with a body part 5 having an opening or recess 6 to receive the stem or shank part 7, of the ivory bead 8, which is the part of the sight that the user of the firearm observes when the gun is discharged. The axis of the opening 6 is parallel to the axis of the barrel of the gun and at right angles to the stem a.

The threaded stem 4. is of such length that it extends only to the inner surface of the barrel, as shown, when the sight is turned down close to the barrel. By forming the stem with athread there is clearly no danger of the sight being blown out or moved from its fixed position by reason of the internal pressure due to the discharge.

The shank 7 of the ivory bead 8 is secured in place in the body part 5 in any suitable manner, as a driving fit, or spinning or crimping the metal down onto the shank. It should be particularly observed that the bead part 8 is down close to the upper surface of the barrel 1, whereby the user will not be misled by any other part of the sight structure, the advantages of which are obvious.

From this description it will be seen that I have provided a simple and inexpensive structure for securely retaining a front gun sight in place without any danger of its being displaced; also one that can be readily distinguished by the user, and one which will permit the sight to be turned down close to the upper surface of the barrel.

hat I claim is:

In a front gun sight, the combination, of a gun barrel formed with a threaded opening therein, a member having a threaded stem to engage said opening, the member having a recessed part in one end to receive a white colored ivory bead, which comprises the sight proper, the bead and threaded stem construction being so arranged to permit the sigl'lt as a whole to be turned down close to and in contact with the upper surface of the gun barrel, the bead being of a size to cover and conceal the whole end surface of the member without leaving any space between the sight and the barrel. whereby only the head of the sight is visible to the user, as described.
